Dambovita - 50 km between good quality and ecological disaster
Cinq Continents , 2011,
Abstract: Dambovita - 50 km tra buona qualità e disastro ecologico. Dambovita è il principale corso d'acqua che attraversa Bucarest. Quindi, è l'acqua collettore delle acque reflue, industriali e pluviale generati all'interno della città, arrivando prima attraverso la rete fognaria al impianto di depurazione Glina. Quest’ultimo, però, non è ancora funzionale, dumping le aque reflue nel fiume senza trattamento preliminare, che portano ad una forte degradazione dellaqualità dell'acqua, che è in clasa scarsa qualità incorniciata iniziando dall punto della perdita Glina fino a che la fuoriuscita in Arges. Fare determinazioni delle principali proprietà fisiche e chimiche delle acque in punti scelti in modo da fornire una panoramica di come la loro qualità è subito a causa delle fonti diinquinamento nella zona di Bucarest, un generale degrado del fiumeDambovita da monte a torrente fu trovato, le cui acque contaminate influiscono la qualità condizione dell collezionista Arges, così come la freatica che si trova ad una distanza di diverse centinaia di metri da esso.
Analisys of the General Management Functions in Comparison with the Management Applied in Police

Acta Universitatis Danubius : Administratio , 2012,
Abstract: The general principles of management are valid in any institution, but the specific aspects of the structures within police impose a different approach due to the structural particular aspects, such as: the organisational climate, the complexity of the missions, the relationships between seniors and juniors, the specific liability which rises whenever the given disposals are not performed with maximum of efficiency, the stake being incomparable greater than in any other organisation. We need to know and apply the notions of the management and managerial communication, so that to fulfil these desiderata. The police management represents the activity which consists in leading a group of people, in a given situation, in order to collectively reach the goals, in accordance with the desired finalities aimed by the general strategy of M.A.I.
Challenges of the Knowledge Society , 2011,
Abstract: We have analyzed the impact the introduction of art. 741 penal C. over a certain category of infractions, respectively over the economical nature infractions. Harmonization of such recent norms with the already existent legislative framework rises a series of questions and possible practical problems. Also, we have considered interesting to appreciate if such changes are sufficient or there is not a conflict between the punishments set forth by regulators for each of such infractions. Should the answer be yes, there should be considered the possible conciliation methods.

Abstract: TRENDS IN VARIABILITY OF WATER FLOW OF TELEAJEN RIVER. In the context of climate change at global and regional scale, this study intends to identify the trends in variability of the annual and monthly flow of Teleajen river. The study is based on processing the series of mean, maximum and minimum flows at Cheia and Moara Domneasc hydrometric stations (these data were taken from the National Institute of Meteorology and Hydrology). The period of analysis is 1966-1998, statistical methods beeing mostly used, among which the Mann – Kendall test, that identifies the liniar trend and its statistic significance, comes into focus. The trends in the variability of water annual and monthly flows are highlighted. The results obtained show downward trends for the mean and maximum annual flows, and for the minimum water discharge, a downward trend for Cheia station and an upward trend for Moara Domneasc station. Knowing the trends in the variability of the rivers’ flow is important empirically in view of taking adequate administration measures of the water resources and managment measures for the risks lead by extreme hidrologic events (floods, low-water), according to the possible identified changes.
Urban Growth and Its Impact on Cityscape: A Geospatial Analysis of Rohtak City, India  [PDF]

Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.41002
Abstract: Rohtak is one of the eight priority towns (Regional Centres) of National Capital Region (NCR) Regional Plan 2001. It lies 70 kms north-west from Delhi, the National Capital of India. Located at 28?41'1'' North latitude and 76?12'42'' East longitude in the NCR region of Haryana state on National Highway No. 10, it spreads over 100.57 km2. Its population was projected to grow to 500,000 by 2001. Despite its nearness to the national capital it did not attract investment and the rate of urbanization remained low. Rohtak city grew slower than the state of Haryana in the three decades ending in 2001. On being declared as Municipal Corporation in 2010 urban growth of Rohtak took place in the form of extension in territorial jurisdiction and inclusion of urbanized eight villages. The new economic environment demands sustainable land management. Spatial information of land use/land cover types and their change detection in time series are important means for city planning and undertaking development activities. The present work is undertaken in that spirit. It has analyzed the relationship between urban growth and land use changes and their impact on Rohtak city. The period of focus is from 1983 to 2010. Both primary and secondary sources of data have been used for the present study. Secondary sources of data—guide map, topographical sheet and high resolution satellite imageries have been used to detect land use/land cover changes from the study area whereas primary source of data include ground truth and photographs from the field.
Recent Active Fires under El Niño Conditions in Kalimantan, Indonesia  [PDF]
Nina Yulianti, Hiroshi Hayasaka
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.43A087

Analysis of the most recent 10-year periods (2002 to 2011) of MODIS hotspots data (fires) and precipitation in Palangkaraya and Pontianak was carried out to identify seasonal and spatial fire occurrence in Kalimantan under El Nino conditions, and to asses future forest condition in Kalimantan. Most data was tallied every 10-day to analyze seasonal and spatial fire occurrence. Seasonal and spatial analysis results for severe fire years, namely 2006 and 2009, under El Nino conditions were as follows: the severest fire incidents for whole Kalimantan occurred in October in 2006 under the driest conditions in both Palangkaraya and Pontianak. The severest fires for the Mega Rice Project (MRP) area and its vicinity occurred in late September in 2009 under the driest conditions for Palangkaraya. Fire activities in the last 10-year in south Central Kalimantan were severe than other areas in Kalimantan. This may be explained by different dry conditions of peat. Namely, the peat in the southern part of Central Kalimantan could become dryer under the relatively longer dry season (about 3-month) compared with other areas (dry season in West Kalimantan is only 2/3-month). One of spatial analysis results clearly showed a so-called a fire belt shape arising from severe fires that occurred mainly on the southern coastal peatlands from West to Central Kalimantan in mid October in 2006.

Biophysics and Cancer: The Electromagnetic Fields Produced by the Mitochondria and Its Effect on the Cell’s Metabolic Regulation  [PDF]
Nina Bardi de Alvarez
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2014, DOI: 10.4236/jemaa.2014.610033
Abstract: We studied the interactions between electromagnetic fields (EMF), the Hydrogen isotope (H1) and the biophysical process that precedes the biochemical expression of the cell’s energetic mechanisms. The hydrogen isotope, being the simplest atom, its manipulation is more technically feasible. In addition of its importance in metabolic energy driving reactions due to its reductive power, the hydrogen atom seems to be a necessary cofactor and driving force to induce, foster and/or restore oxidative phosphorylation in the cancer cell. Normal cells require a higher level of energy to attain and sustain the order, communication and direction necessary for the maintenance of the differentiated state. When cellular aerobic energy mechanisms are damaged, the energy is not enough to sustain the complexity and specificity of differentiation and therefore it can only either die or transform to a simpler state (less differentiated) that requires less energy in order to survive. This is the genesis of the malignant state. The interaction of the H1 with the EMF produces a change in the permitivity of the mitochondrial membrane that favors the release of energy allowing for the oxidative phosphorylation to proceed. We propose that this interaction of the EMF and the H1 can be manipulated in such a way that it would be capable of clearing interferences of fields that may favor transformation to the malignant state.
